我正在学习John Conde关于Authorize.net使用PHP和错误检测的信用卡输入表单的教程。
它非常完美,但我决定添加输入框来输入付款金额,并删除了不必要的发货地址要求;
现在,当提交的表单输入不正确或为空时,它们不再变为红色,“金额”框也不会真正识别它是空的还是已填充的。错误框仍然会弹出,用于提交不良信用卡。
这是页面(去掉了简化故障排除的设计);

编辑:删除了与信用卡无关的代码以及州和年份到期日期等内容,使其更小。最底部的PHP代码用于红色错误弹出框,当用户错误填写表单时,该框会显示给用户。
如果有人想比较的话,我在教程的这一部分:

最后,我想把checkout按钮移到div表单之外,所以我做了这样的按钮(在设计的页面中,而不是上面的例子)
</form> <br>
<form id="myform"><p class="center">
<button form="myform" input type="submit" value="Checkout">
</p></form>
按钮可以工作,但它不会将值显示为我(WIP)设计的页面上的标签。
